Mackenzie Molner and Mark Arnold lead the U.S. Junior Invitational (June 17-21, Tampa) with 5/7 and two rounds to go. Meanwhile, the concurrent Cadet is down to the wire with just one round left. Evan Ju dominated for most of the event but lost to Warren Harper in round seven- Harper and Ju are now tied for first with Robert Lau just half a point behind.

Mackenzie caught up to Marc with a seventh round win over Teddy Coleman.

14...Bb7 was a big mistake, allowing a forced tactical variation for Mackenzie beginning with 15. fe6. Because of 21...Nf3+!, White's position still required some work to win. Instead of 14...Bb7?, Teddy could have tamed White's pieces (especially the bishop on d3!) with 14...Ne5.
